Wi-Fi-based people counting
Wi-Fi people counting turns the access points you already run into a footfall sensor network. It picks up the signals phones give off as people move, so visitors need no app and take no action. From those signals it measures counts, dwell, paths and conversion across whole spaces. It needs no cameras or extra hardware and works without personal data.
Works with Cisco, Ruckus, Aruba and other enterprise Wi-Fi, with no new hardware.

What makes it work
-
Uses existing infrastructure
Works with leading enterprise Wi-Fi platforms (Cisco, Ruckus, Aruba and more) so most venues can start measuring with no new hardware.
-
Privacy-first by default
Device signals are anonymised and aggregated into counts and flows. No individuals are identified and no personal data is kept.
-
Whole-space coverage
Where a camera covers an island beneath it, Wi-Fi measures the entire area as one continuous flow. See counts, movement between zones, dwell and conversion.
-
Calibrated to reality
Manual control measurements are matched to our own data and feed the model, so the numbers mirror what happened.
How it works
-
Measure
Phones with Wi-Fi on emit signals as people move. Your existing access points pick them up without an app, a login or any action from the visitor.
-
Anonymise & filter
Personal data is irrevocably deleted, leaving only anonymous statistics. AI filtering strips out noise like randomisation, spoofing, stationary devices and staff.
-
Process & calibrate
The statistical engine extrapolates from complete visits to the true population, fills path gaps, and calibrates against manual control counts.
-
Deliver
Anonymous metrics are delivered through the API and your dashboards the day after the visit. Recurring visits within the same day can also be measured.
What data you get from Wi-Fi
Wi-Fi is Bumbee Labs' macro method, strongest at covering whole spaces and the journeys across them. Typical metrics from a Wi-Fi installation:
- Visitor count (total) and unique visitors
- Dwell time, per zone and overall
- Visitor paths & flows between zones and between sites
- Zone data & correlation, and anchor positions
- Passers-by and capture rate (passing → entering)
- Peaks & lows and long-run trends
For exact line-crossing in/out and live occupancy at a specific door, pair Wi-Fi with cameras/3D sensors. See the full method-by-method grid.

Why measure whole spaces with Wi-Fi people counting?
Wi-Fi people counting measures behaviour across whole spaces from infrastructure you have already paid for, and visitors stay anonymous. You may sense that some areas pull traffic and others don’t, that certain hours are dead and that campaigns sometimes land. Without data those remain impressions, and impressions are a costly basis for decisions on staffing, layout and rent. A camera is precise, but only at the door where it is mounted. The page on GDPR-compliant footfall analytics explains how the method meets GDPR.
Where it fits best
Wi-Fi counting suits larger indoor and outdoor spaces that already have access points, such as shopping centres, city districts, transport hubs, retail and large venues. For entrances that need exact line-crossing counts, it can be combined with our camera and sensor methods in a hybrid setup.
Built on the network you run
Wi-Fi counting is hardware-agnostic. The major enterprise platforms are already integrated, so it can read from the access points you operate today. → Works with enterprise Wi-Fi including Cisco Spaces, Cisco Catalyst, Cisco Meraki, RUCKUS One, RUCKUS SmartZone, Aruba Central, ArubaOS / ALE, Juniper Mist, Huawei and Extreme Networks. See all supported networks and platforms.
Does Wi-Fi people counting work for occupancy monitoring?
Wi-Fi analytics supports occupancy monitoring as well as counting visitors as they arrive. It shows how many people are present in a space and how that number builds or clears across the day. It uses the same access points, needs no cameras or personal data, and delivers occupancy figures to the same dashboards and API as your other footfall metrics. Standard metrics are ready the day after the visit. For threshold alerts, the Crowd Alert add-on works in near real time. Live occupancy at one specific door needs cameras or 3D sensors alongside Wi-Fi. Teams with sites across Europe and North America measure foot traffic at all of them on one platform. The article on occupancy and crowd comfort looks at how occupancy affects the way a venue feels to visitors.
Why this is not Wi-Fi tracking
Wi-Fi tracking needs a visitor who can be singled out, and this method leaves none. The Wi-Fi signals phones emit are gathered passively, with nothing installed on any phone. All personal data is then irrevocably deleted, never hashed and kept, and only anonymous, aggregated statistics remain: counts, dwell, flows and trends. IMY, the Swedish Authority for Privacy Protection, examined the method in a supervisory case and concluded that no individual can ever be identified. The IMY decision sets out what it examined.
How does a Wi-Fi people counter work, and how accurate is it?
A Wi-Fi people counter turns the access points a venue already runs into the sensor. Phones give off short signals as people move, the network picks them up, and the signals become counts, dwell and flows. Accuracy varies with the venue, with the number and placement of access points and with the calibration, so each deployment is checked against manual control measurements matched to our own data. How each method is verified is on the people counting accuracy page.

Wi-Fi vs other counting methods
Wi-Fi covers whole spaces and the journeys across them. Pair it with cameras or cellular where you need point precision or wide-area catchment.

Approved and validated
Wi-Fi counting from Bumbee Labs is the only footfall method in Europe approved by a data protection authority, and it has been validated by academia, partners and customers. You get full insight with no personal data.
By partnering with Bumbee Labs we have opened the door for our end-customers to radically change the way they plan and prepare for the future. They can look to attract more visitors and reform their offer to tailor it to the wants and needs of individuals in and around their sites. This can all be achieved without any additional investment in physical hardware thereby reducing costs, while bolstering their return on investment.
Frequently asked questions
Does Wi-Fi people counting identify individual visitors?
No. Personal data is deleted irrevocably and only anonymous statistics are kept, in the form of counts and flows built from anonymised, aggregated device signals. The method is designed so that no individual can ever be identified.
Does Wi-Fi people counting need new hardware?
Usually not. Wi-Fi people counting works with many of the enterprise access points venues already run, with Cisco, Ruckus, Aruba and others integrated, so most sites can start measuring on their existing network. A few access points can be added where a site needs higher accuracy or extra coverage.
How is Wi-Fi people counting different from camera-based counting?
A camera measures a small area directly beneath the sensor and is highly precise at that point. Wi-Fi follows the whole space as one continuous flow, so it can describe dwell, paths and zone correlation across an entire store, mall or city centre. Many venues use both.
How accurate is Wi-Fi people counting?
Accuracy is high. The exact figure depends on the venue, on the number and placement of access points and on how the installation is calibrated. Every deployment is checked against manual control measurements matched to our own data and tuned to the space. Where higher precision is needed, Wi-Fi can be combined with other methods.
Is Wi-Fi people counting from Bumbee Labs GDPR-compliant?
Yes. Personal data is deleted irrevocably at the source, so only aggregated statistics remain. A European data protection authority has reviewed and approved the method.
What is a Wi-Fi people counter?
A Wi-Fi people counter uses the access points a venue already operates to count people. It turns ambient phone signals into counts, dwell and flows without an app, a login or new hardware. No personal data is kept, and the method is the only footfall method in Europe approved by a data protection authority.
